Optical properties of one-dimensional nanomaterials based on small organic molecules

近年来,一维有机小分子微纳材料因为其新颖的光学性能和在未来小型化器件中的广泛应用,受到了人们越来越多的关注.相比于传统无机半导体材料,有机小分子材料具有结构多样性、功能可设计性、易大量制备、易机械加工等显著优势.本文将从一维有机小分子纳米材料的制备方法、形貌调控、光学性能(如光波导、受激发射、电致发光等),及其在光学器件上的应用出发,对近十年来的相关研究进展及成果进行总结和介绍.

One-dimensional （1D） nanomaterials synthesized from opto-functional low-molecular-weight organic compounds have drawn great interests for their unique optical properties and potential applications in high speed miniaturized photonic integrations.Compared with their inorganic counterparts,organic nanostructures offer advantages such as their high reactivity,ease of chemical doping and convenience in processing at low temperature.In this article,we begin with a general overview of recent progress in this research area.After that,the construction strategies for achieving 1D nanostructures from small organic functional molecules are introduced.Then we focus on the unique optical properties induced by molecular aggregation in the nanostructures,such as optical waveguide,stimulated emission and electroluminescence.This article concludes with a summary and our perspective about future development in 1D organic molecular nanomaterials and organic integrated photonic devices.
